Problems solved by technology

Therefore, in all possible value combinations of the current RI and the field indicating the total number of space-frequency combining coefficients corresponding to all spatial layers, there is a certain redundancy state, that is, in the prior art, when used to indicate the corresponding When the value of the field of the total number of space-frequency combination coefficients is less than α*R, the value is meaningless and has not been used at present

Abstract

The present application provides a communication method and device. The method includes: effectively utilizing the redundant states that appear in the indication information combination of the current CSI part 1, and using these redundant states to indicate more information without introducing additional overhead, so that the network device can more accurately know the downlink channel Status information, adjust the configuration in time, so as to obtain the best compromise between system performance and overhead.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a communication method and device. Background technique [0002] The multiple input and multiple output (Multiple Input and Multiple Output, MIMO) technology is the core technology of the Long Term Evolution (LTE) system and the fifth generation (5th generation, 5G) new radio (new radio, NR). [0003] Based on all or part of downlink channel state information (Channel State Information, CSI), precoding (Precoding) technology can effectively improve signal transmission performance and system capacity. For a frequency division duplexing (Frequency Division Duplexing, FDD) system, the uplink and downlink use different frequency bands, and the uplink channel cannot be used to obtain the downlink precoding matrix. In an existing wireless communication system, a downlink optimal precoding matrix is ​​generally obtained by feeding back a precoding matrix or a...
